Which of the following conditions is characteristic of logistic growth?

Fixed carrying capacity

The correct answer is Option (3) -Fixed carrying capacity

Logistic growth occurs when there is a fixed carrying capacity, meaning that the environment has a limited capacity to support a population. In this type of growth, the population initially experiences exponential growth, but as it approaches the carrying capacity, the growth rate slows down and eventually levels off. The carrying capacity represents the maximum population size that the environment can sustain with its available resources.

Option (3) is the correct answer. Logistic growth is characterized by the presence of a fixed carrying capacity, which imposes a limit on population growth.

Option (1) is not accurate because logistic growth takes into account the resistance from increasing population size as it approaches the carrying capacity.

Option (2) is not correct because logistic growth assumes that food resources are not unlimited and will eventually become a limiting factor as the population size nears the carrying capacity.

Option (4) is not accurate because all of the mentioned conditions are not applicable to logistic growth. The key characteristic of logistic growth is the fixed carrying capacity, while the other options may or may not be present.
